suLKY-PLow.

SPECIFICATION forming part of Letters Patent No. 286,517, dated October 9, 1883.

Application filed April 28, 1883. (No model.)

To aZZ whom it may concern:

Be it known that we, HARRY *vVIAnD and XVILLIAM R. BULLOCK, of Syracuse, in the county of Onondaga, in the State of NewYork, have invented new and useful Improvements in Sulky-Plows, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description;

This invention consists in a novel construction and combination of a sulky and devices for adj ustably suspending therefrom a plow in such a manner that by the manipulation of a single lever the sulky can be maintained in a elevation of our improved sulky-plow.

. by the tongue T, firmly attached thereto.

horizontal position while the plow is in as well as out of the ground, and the adjustment of the sulky is facilitated by the weight of the 1 driver seated thereon, and the lever is thus relieved of the greater portion of the strain, all as hereinafter more fully explained, and specifically set forth in the claims.

In the annexed drawings, Figure I is a side Fig. II is a rear end view of the same. Fig. III is a plan view with the seat broken away to better illustrate the more essential features of the invention. Fig. IV is an enlarged longitudinal section of the shifting-lever and its connection with the crank-axle and ratchets. Fig. V is rear face view of the same, illustrating the operation of the guard for automatically throwing the dog out of its engagement with the ratchet of the carrying-wheel. Fig. VI is a detached view of the crank-axle. Fig. VII is a transverse section on line a: m in Fig. III, showing the arrangement of the friction-roller which forms the bearing for the plow-beam when the plow is carried in an elevated position under the sulky. Fig. VIII is an enlarged side view of one of the collars by means of which the plow is confined laterally in its position on the sulky, and Fig. IX is an isometric detail view of said collar.

Similar letters of reference indicate correarching or in the form of the three sides of a rectangle, supported in an upright position The drivers seat S is supported on the usual standard, S, which is secured to the tongue at its junction with the frame A, and extends rearward therefrom, so that the entire weight of the driver comes onto the sulky. The extremity of the frame A, on the land-wheel side of the sulky, has integral with it a rearward projecting serrated collar or disk, to which is fitted a correspondiugly-serrated collar, 1), which is cast in one piece with an arm, 0*, the opposite end of which is provided with a sleeve, it, through which the inner end of the axle a of the land-wheel passes. A nut appliedto said axle at the inner end of the sleeve firmly connects said parts. The two collars p pare adjustably clamped together by means of a bolt inserted through the center thereof, as shown. The before-described connection of the axial support of the land-wheel with the main frame Ais very rigid, and yet allows the coupling or supporting arm r to be turned, so as to carry the land-wheel higher or lower in relation to the furrow-wheel, the position of which latter is controlled by a single lever, in the manner hereinafter described.

B represents a crank-axle, one arm, I), of which terminates at and has its extremity pi voted to that of the frame A, adjacent to the land wheel W. The other arm, I), of the crank-axle is of greater length than the arm I), and inclined rearward, and terminates in a horizontal extension forming the axle a. for the furrow-wheel V. The arm I) is connected with the main frame A by an arm, 0, rigidly attached to the arm I), and pivoted to the extremity of the frame A nearest the furrowwheel W, the two pivotal connections of the opposite and in line with each other. plow P is connected to the cranlraxle by a shoe, N, clamped onto the plow-beam, and pro vided above said beam with a suitable bearing for the crank-axle B. A cap, I, placed across said axle and bolted to the shoe N, perfects the attachment of the plow. Said attachment, however, is adapted to slide longitudinally on the crank axle l3, and thus shift the plow bodily laterally, said shifting allowing the plow to be adjusted so as to take more or less land or cut a furrow of greater or less width, and at'the same time maintaining the plow parallel to the line of draft, thereby obviating the cramping of the sullry incident to a deflection of the tongue, which latter means of adjusting the plow has heretofore been resorted to. We secure the plow in the required position by The means of collars M M, clamped on the crankaxle at opposite sides of the shoe N. Said collars we construct as illustrated in FigsVIII and IX of the drawings, for the purpose of reducing the cost of their manufacture, facilitating their application and removal when required, and rendering them more effective in their opera tion, each of said collars being composed of two parts, 10 and w, which do not quite reach around the axle B. The part w is provided above the axle with an upward projection, 5, and with an eye, 6, insaid projection. The part w is formed with an upward-projecting hook or curved tongue, 7, which is adapted to pass through the eye 6 and interlock with the solid portion above said eye. The lower extremities of the aforesaid two parts are ex tended below the axle, and are provided with holes for the reception of the bolt 8, by which the two parts are drawn together and clamped on the axle B. It will be observed that the described construction of the collar M saves the expense of drilling holes for the hinge-pin of the two component parts, and allows the latter to be easily molded and cast and readily put together and applied to the axle, and since the free ends of the two parts do not quite meet, they can be drawn together sufficiently to obtain a firm hold on the axle.

L denotes the shifting-lcver, provided at its lower end with an eye, a, through which the f arrow-wheel axle a is extended. Aset-screw, a, passing through the eye a and engaging the axle a, rigidly secures the lever on said axle. The lever has projecting fromits front edge an arm, d, which is pivoted on the outer end of the pin or bolt '0', which couples. the long arm I) of the crank-axle with the frame A, said pivot serving as a fulcrum for the lever L.

It will .be observed that by the described arrangement of the long arm I) of the crankaxle and the lever L, lying back of the fulcrum c, which latter is in line with the pivot of the opposite end of the crank-axle, the furrowwheel axle a is nearly directly under the fulcrum 12 when the lever is thrown into its extreme rearward position and the crank-axle lowered to throw the plow into the ground, thus throwing the axle a into its greatest distance beneath the fulcrum when the plow is in operation and the furrow-wheel travels in the furrow, and thereby maintaining the sulky in a horizontal position. The forward thrust of the lever L swings the axle a rearward, and simultaneously raises the main or central portion of the crank-axle. The latter raises the plow out of the ground and draws it forward or toward the sulky, while the former throws the furrow-wheel backward and lowers the sulky so as to bring it into a horizontal posi tion when the plow and wheel leave their respective furrows hence one and the same lever accomplishes the adjustment of the sulky, and this adjustment isfacilitated and the lever relieved of the greater portion of the strain by the comparative slight travel of the axle a past the fulcrum and by the weight of the driver coming directly on the fulcrum.

R denotes a quadrant or segmental rack, having its teeth or notches on the under side, for the purpose hereinafter explained. This quadrant we pivot on the fulcrum-pin 'u, so as to maintain it concentric therewith. The segment or rim of the quadrant we provide with slots Z Z, through which pass the bolts m m, by which the quadrant is fastened to afixed bearing on the frame A. Said slots allow the quadrant to beturned on its pivot and clamped in such a position. as to allow the lever L a greater or less thrust in either direction past its fulcrum, and thus regulate the action of the cranked axle, so as to carry the plow a greater or less depth into the ground and the furrowwheel a greater or less distance beneath the fulcrum, as well as back and forward there of. The aforesaid adjustment of the quadrant carries with it the guard 70, hereinafter described, and thus simultaneouslyadjusts the action of the dog 0 in conjunction with the ratchet f, which compels the furrow-wheel to lift the plow.

f is a ratchet-wheel which is integral with or rigidly attached to the hub g of the furrowwheel.

In a longitudinal guide or way, a, on the lever L slides rectilineally a duplex dog, 6, in

the form of abar, having its lower extremities adapted to engage with the teeth of the ratchet wheel f.

From the back of the dog eprojects atooth, 71 which is in such. relative position that it can engage with the teeth of the quadrant R, andbecomeliberated therefrom withoutthrowing the extremity of the dog into engagement I with the ratchet f, before described. The dog a is held normally. in engagement with the quadrant by means of a spiral spring, 8, surrounding the ,upper end portion of the dog, which is shaped to accommodate said spring, the spring resting with its lower end against lugs l 1, cast on the lever L, and exerting an expansive force against a collar or pin, 2, on the dog. A small handlever, 0, is pivoted to the mainlever L and connected to the dog 6 near the upperend thereof. By pressing down said lever 0, the dog e can be pushed far enough to cause it to engage with the ratchet f on the hub of the furrow-wheel, and thereby compel said wheel to swing the lever L' forward and the crank-axle upward, and thus throw the plow out of the ground and the furrow-wheel rearward to level the sulky. This action by the furrow-wheel, however, is not always desirable. In order to give the operator full control of the aforesaid action, we provide the lever L with an extension, L, preferably formed of wood and bolted to the iron lever L. On this extension we hinge another small lever, which is provided with apush-bar, e, the movement of which is limited by a pin, 3, projecting from the handle-extension L and through a slot, 4, in the push-rod. Said slot is of sufficient length that while allowing the push -'bar to'force the dog out of engagement with thequadrant B it atthe same time preventsthe engagement of the lower end of the dog with the ratchet f. This arrangement allows the operator to swing the crank-axle in the manner hereinbefore described without bringing into action the ratchet f, fixed to the hub of the furrowwheel.

Heretofore the connection between the lever and the ratchet on the wheel has generally been made bya separate and distinct pawl pivoted to the lower end of the lever and operated by'an extra rod connected with said pawl and with a supplemental lever pivoted to the upper end of the main lever; but it is obviouslthat suchdevices have more joints,

that are liable to wear and work loose and rattle, andare neither so compact, stable, and durable, nor so positive and reliable in their 'operatiolnas our improved connection between the lever and the wheel and quadrant.

In order to guard against accidents from' neglect to throw the dog in due time out of engagement with the ratchet-wheel f, we pro} vide the forward end of the quadrant with a sloping upward projection, 71?, and fix to the back of the dog e a lug, the encounter of which with the projection is compels thedog e to rise and clear the ratchet f.

E represents a roller pivoted horizontally and at right angles to the line of draft on the foot-rest l? or other suitable support underneath the tongue T, said roller forming an anti friction bearing for the plow-beam when theplow is raised out of the groundand carried in an elevated position underneath the snlky. v
